GEORGE ROBERT SISTERSON, OF LONDON, ENGLAND, ASSIGNOR TO SUPERHEATERS,

. LIMITED, OF LONDON, ENGLAND.

STEAM SEPARATOR AND WATER.

To all whom it may Concern:

Be it known that I, GEORGE, ROBERT Sis- TERsoN, a subject of the King of Great Britain andlreland, and residing at 12 Great James street, Bedford Row, London, W.C., England, have vinvented a certain new and uselul Steam Separator and Heater, of which the following is a specification.

Thisinventionrelates to the treatment of steam foarl steam engines, and the steam for locomotives.

The object of the invention is to separate the water Icarried over with the steam from the boiler,.so that only dry steam is allowed togo to the cylinders of the engine, and,

that economy is eiiected.

Theinventiorr* consists in interposing a4 separator in the. steam ma1nso as to sepaf rate the Water carried over with the steam from the boiler, and in combiningvnth the separator a heater, adapted to receive the lseparated water and to vaporize'the same, so

that thesteam so ener-ated eanbe fed to thel steam which owsv to the cylinders',

u thereby' nl" only insuring dry steam, but effecting ecenom `The. `accompanying drawings illustrate several modes of carrying out the invention.

c, the water carried over with the steam is separated and is thrown donn into one side, g, of the header, z, of a heater of any suitable form. The heater in the form shown com rises a header, 72 divided into two com part ents, g, t', which are connected by a number of U-tubes, k, the U-tuhes being massed into some of the fire tubes, Z, of the' 011er. Thus the water or wet steam which is thrown down into the compartment g, of

the header, and which passes through the U-tubes, k, is. heated, the Water being vaporized and the steam to a certain degree superheated. This steam passing from thev compartment, t, of the header mixes With the steam which llows through the perforaf tions, c, into the branch, d, and thence, by the steam pipe, f, to the cylinder'. Obv1 busty, when there is but little water thrown down into the heater, some of the steam maypass freely through the heater, being thereby superheated or dried, and supplementing the separated steam which is led direct to the branch, d, thereby further raising` the tem-:.

tubes, n, maybe extended straight across the ends of a row of tire tubes, being bent with an elliptical or circular bend, o, and a furtherl'oop, p, as show r in Fig. 2, care being taken to arrange the tubes so that a cleaning brush may be inserted in all the fire tubes. Obviously .the tubes, '11', may be bent or curved in any suitable manner, so as to give the desired heating surface.

ln carrying out the invention according to a further mode, as illustratedin Fig. 4, the tubes, n, of the heater, instead of passing the steam directly by `a singleA coil from the branch, l), to the branch, d,inay lead it into one or more intermediate chambers or headers, s, thusy extending the path of the steam through the tubes, n, and 'increasing the `heatingsurlac'e of the heater. lt will be understood that any other suitable form of I inder, these tubes, q, adding` to theavailable .10.

heater and separatorniay be employedfor instance, a heater comprising a divided header-and connected by anumlger of con oentrioalljy arranged tubes:

In the example sho'efn in Fig. It a knor'n arrangement vof a number of tubes, q, are shown, in substitution for lthe usual single steam pipe 1ehich leads thestean'l tothe cylheating surface within-the smoke box and being' connected at ,their ends -to suitable headersf-for instance, as indicated' at r.

ln the further forni of apparatus shoisnin Fig. 5, the steam passes from' the branch, a,.l

Figs. 6 and' .7r diagrammatically illustrate the application of the invention to marine:

boilers of the Scotch type, Fig. 6 showing a case 'a here a heater comprising tubes, n, arranged in the 'smoke stack or lip-take, t, is used, v vhereasl Fig, 7 sho s 'a heater having tubes, 7c, entering some of the '-ire tubes, l, of the boiler-. In marine boilers it .mayY bedesirable to arrange the-separator outside of thefuptake, t, for instance, as indicated in When-desired,without interfering. ith the lmore than one header may be used-for cach Working ot' the other part. It is obvious that heater lparticularly the` forms shown .in Figs. 1, 6 and 7, and it Vmay be fittedvfithany desired numler of tubes; or; a comparatively large header, divided into a series OLC-hambers, may be adopted. 4lnsteadof employing A two combined separators and heaters, independently mounted upon vthe brarmhl lor steam pipes as hereinbefore described e ith reference to Figs. 1,2, 3 and 4 one separator may be fitted on thesteam main before it branches into two, thi ingle separator'supplvingreithefdgebeader or two or more eisers' small headers which can lead the.. steam generated from the separated Water or the Superf heated steam into one or both of. the branch pipes. 'it is obvious that the return ends of pipes, n, (Figs. 2 and 3)can be connected to any convenient point of the pipe, f, separation ot the eater being effected by simply branching the "i`-piece.

rlhe invention is ap lcable to the treatment of steam from otA er boilers than locomotive or marine boilers, the heater and separatei" being suitably modified to suity the typel of boilers to Whioh the invention is tobe applied. Vv` y Having thus described my invention what vlfelaim as new Yarid desire to secure by Letters Patent is :ef

- l. In combination a steam main, a separavtor interposed'therein comprising an inlet and an outlet compartment and means for bailiincf the steam -assm from one oom aartn l e ment to the otoer, means connected Wlth the inlet compartment for receivingfthe water. and Wet steamdeposited therein, means for heating said receiving means and connection from the latter tothe outlet compartment of the separator substantially as and `for the purposes hereinbefore set forth.

2. In combination a steam main, a separaf'tor interposed therein comprising an inlet and an outlet compartment, a perforated Wall dividing said compartments, a series of Atubes connecting the bottom of one compartment with the bottom ofthe other and means for heating said tubes substantially as and for the purposes hereinbefore set iorth.

In a locomotive fire-box, a steam main,

va'sepr.rator therein, 'comprising inlet and outlet compartments, means forbaffling the steam passing from the former to the latter, and tubes disposed in front of the usual lire tubes ofthe boiler, said tubes being connect- 1 ed to the aforesaid compartments of the separator to receive the deposited Water and Wet steamA and to 'return it as dry steam to the main. y

4. In a locomotive fire-box, a steam-main, a'separator thereon comprising inlet and outlet compartments, perforated Walls between the coinJar'tments'for battling the steam assing t erethrough, and tubes disposed in ront of the usual boiler fire tubes, said tubes being connected. to the aforesaidcompartments of theseparator to receive the deposited Water and Wet steam and to return it as dr;r steam to the main..
